Jensen Precast manufactures and supplies the industry’s finest-quality polymer concrete, underground utility enclosures. The polymer concrete handholes come in Tier 15 or Tier 22 loading with a variety of lid options and types. While we’ve kept a focus on interchangeability, we offer improvements to traditional enclosures with proprietary features that facilitate installation, enhance security, add longevity, and provide unsurpassed surface traction options.
